Life in Christ›SECTION ONE MAN'S VOCATION LIFE IN THE SPIRIT›CHAPTER TWO THE HUMAN COMMUNION›III. Human Solidarity
Socio-economic problems can be resolved only with the help of all the forms of solidarity: solidarity of the poor among themselves, between rich and poor, of workers among themselves, between employers and employees in a business, solidarity among nations and peoples. International solidarity is a requirement of the moral order; world peace depends in part upon this.
